In the Nectar of Instruction,
Text six, Srila Rupa Goswami cautions that it could be very
offensive to judge or evaluate a devotee on the basis of his
physical aspects. A pure devotee, being transcendentally situated
in Krishna consciousness has nothing to do with the physical body
or with aspects linked to it, like birth, family, relatives,
gender, health or good-looks.

Being situated in his original Krsna conscious position,
a pure devotee does not identify with the body. Such a devotee
should not be seen from a materialistic point of view. Indeed,
one should overlook a devotee's having a body born in a low
family, a body with a bad complexion, a deformed body, or a
diseased or infirm body. According to ordinary vision, such
imperfections may seem prominent in the body of a pure devotee,
but despite such seeming defects, the body of a pure devotee
cannot be polluted. It is exactly like the waters of the Ganges,
which sometimes during the rainy season are full of bubbles, foam
and mud. The Ganges waters do not become polluted. Those who are
advanced in spiritual understanding will bathe in the Ganges
without considering the condition of the water.
